JAMES J. GILMORE, OF ALLEGHENY, PENNSYLVANIA.

BINDER.

SPECIFICATION forming part of Letters Patent No. 602,742, dated April19, 1898.

Application filed March 20, 1897.

To all whom it may concern:

Be it known that I, JAMES J. GILMORE, of Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Binders, of which the followingis a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification, in which- Figure 1 is a perspectiveview of my improved binder. Fig. 2 is a transverse section through theclam ping device. Fig. 3 is a bottom plan view of the clamp detached anddisconnected. Fig. 4 is a side elevation of a modified form, and Fig. 5is a top plan view thereof.

My invention relates to that class of temporary binders in which theupper board thereof is retained in operative position by means of clampsand is designed to afford a simple and effective device therefor.

In the drawings, 2 is the lower or stationary board, having thereon thestationary clamping-bar 3.

4 4 are rods extending from the bar 3 and fixed thereto.

5 is the upper or movable board, having thereon a clamping-bar 6,provided with holes to permit of the passage of rods 4 4 therethrough.

7 7 is the spring-clamp, having upwardlyextending handpieces 8 8.

9 are notches in the ends of the clamp 7 7', designed to impinge uponthe rods 4 4 and serving as guides to keep said clamp in alinementtherewith.

In Figs. 1, 2, and 3 I show the clamp 7 7 in its preferred form, whereinit is represented as being constructed of flat strips or clamping-armsof metal fixed at opposite ends to the clamping-bar 6 by rivets 10 andadapted to contact with at the end and securely grasp the rods 4 4. Inorder to bring the notches of the clamp 7 7 in alinement with the rods 44, I preferably cut away portions of said clamp 7 7, as shown in Fig. 3,and I preferably construct the handpieces, as shown,by securing angledstrips to the clamps 7 7, near the ends thereof.

In Figs. 4 and 5 I show a modified form of Serial No. 628,435. (Nomodel.)

my device, wherein the clamp is represented as two L-shaped strips orarms 7 and 7", pivoted at 11 and having between parts 8 8' the expansionspring 12, adapted to force the ends of the clamp into engagement withthe rods 4 4. The clamping-bar 6 is herein shown as of trough-shapedconstruction adapted to carry the pivots 11, as shown in Fig. 5.

The operation of my device is as follows: The upper or movable board 5,carrying the clamping-bar 6 and spring-clamp 7 7, being removed from therods 4 4, the papers are placed upon the lower or stationary board 2 andclamping-bar 3, the rods 4 4 being inserted through holes provided insaid papers. The upper or movable board 5 is then replaced, as shown,and pressed down upon the papers, the notches 9 in the clamp 7 7 slidingupon the rods 4 4 and held' in close contact therewith by the spring ofsaid clamp, thus resisting any upward pressure that may be exertedthereon. When the papers are to be removed or additional papers are tobe bound thereon, the handpieces S 8 are compressed by the thumb andfinger, whereby the ends of the clamp 7 7 are withdrawn from contactwith the rods 4 4, permitting the upper clampingbar 6 to slide freelyupon said rods.

The advantages of myinvention will be appreciated by those skilled inthe art to which it relates. To the manufacturer it presents aneffective device that is easily and cheaply constructed and to the userone that is easily and quickly operated with one hand. Its parts beingfew in number and of simple construction, it is not liable to get out oforder nor is its operative action liable to fail.

The form and size of the boards 2 and 5 may be altered to suit especialrequirements or may be entirely omitted, the clamping-bars 3 and 6acting with equal eflicienoy. Nor do I confine myself to the relativeproportions of the parts of my device as shown, since they maybe variedas may be desired. Other changes will suggest themselves to the skilledmechanic and may be made without departure from my invention, since Iclaim- In a temporary binder, having clampingbars and upright rods, thecombination therewith of oppositely-extending clamping-arms, I Intestimony whereof I have hereunto set bearing on the rods and adapted tohold the my hand.

clamping-bar, and a handpiece on each of a said arms at a point betweensaid rods, the JAMES GILMORE handpieces of said arms being adapted to be\Vibnesses:

moved simultaneously on compression by the G. I. HOLDSHIP,

hand and to release the pressure on said rods. L. A. CONNER, Jr.
